I'd just like to remind those people (like me), who are slowly making their way from level 50 to 60 and are encountering the experience gates that keep them from the next level/mission, to utilize their duty officer assignments. There are several DOFF missions in the Delta Quadrant that reward upwards of 1,000 skill points and on a critical success, much more than that.
Should you be fortunate enough to have a skill point boost active as well, the experience you can get from letting your DOFF missions run overnight, will easily get you a substantial way through a level.
I personally don't mind having to do a few patrols, PvE queues or Kobali zone missions until the next bit of story content, but then I like taking STO at a slower place so that I don't run out of story content quickly. That said, the DOFFing (that I'd long since set aside), has really helped me through the XP grind.
